- A
Availability Zones
Why wrong: AZs are isolated data centres within regions used for deploying application infrastructure. CloudFront's delivery network uses a different concept — edge locations.
- B
AWS Regions
Why wrong: Regions are geographic areas with multiple AZs. CloudFront has far more points of presence globally than the number of regions.
- C
Edge Locations
Edge locations are the 400+ points of presence in CloudFront's CDN. They cache content locally so users receive it from the nearest possible server, minimising latency.
- D
Local Zones
Why wrong: Local Zones are extensions of regions for latency-sensitive applications near metro areas. They are for running compute workloads, not primarily for CDN caching.

CLF-C02 Cloud Concepts Practice Question
This CLF-C02 practice question tests your understanding of cloud concepts. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Amazon CloudFront serves cached content to users from the closest possible network point, with over 400 such points globally. What are these network points called?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Edge Locations
Amazon CloudFront uses a global network of edge locations to cache and serve content to users with low latency. These edge locations are distinct from AWS Regions and Availability Zones, as they are specifically designed for content delivery rather than compute or storage. Option C correctly identifies these network points as Edge Locations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Availability Zones
Why it's wrong here

Edge Locations
Why this is correct
Edge locations are the 400+ points of presence in CloudFront's CDN. They cache content locally so users receive it from the nearest possible server, minimising latency.

- ✗
Local Zones
Why it's wrong here
Local Zones are extensions of regions for latency-sensitive applications near metro areas. They are for running compute workloads, not primarily for CDN caching.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Edge Locations with Availability Zones or Local Zones, assuming all AWS infrastructure points are similar, but CloudFront's edge locations are a separate global network optimized for content delivery, not for running general AWS services.
Detailed technical explanation
How to think about this question
CloudFront edge locations leverage a global network of over 400 points of presence (PoPs) that cache content using HTTP/HTTPS protocols and support both static and dynamic content acceleration. Under the hood, CloudFront uses regional edge caches (in addition to edge locations) for content that is less frequently accessed, reducing the load on origin servers. In a real-world scenario, a user in Tokyo accessing a website hosted in us-east-1 would receive cached data from a Tokyo edge location, bypassing the need to traverse the Pacific Ocean for every request.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
